A piezoelectric actuator of an ink-jet head includes a vibration plate covering pressure chambers, and piezoelectric elements formed on a surface of the vibration plate. Each of the piezoelectric elements has stacked piezoelectric layers; individual electrodes and common electrodes arranged alternately between the stacked piezoelectric layers; and base portions of a supporting member formed on a surface of the uppermost piezoelectric layer of the piezoelectric layers. In each of the piezoelectric elements, through holes are formed to extend from a surface of one of the base portions, across the stacked piezoelectric layers, and the individual electrodes are exposed in the surface forming the through hole and the common electrodes are exposed in the surface forming the through hole. Conductive materials are filled in the through holes, respectively. Accordingly, a liquid transporting apparatus in which the structure for electrical connection is simple and easily made is provided.
